Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Data on the toxicity to soil macroorganisms and terrestrial plants are available:
In a 14-d toxicity study to earthworms (Eisenia fetida), the LC50 was determined to be greater than 1000 mg test item/kg soil. The NOEC related to mortality and biomass was determined to be 320 mg/kg soil.
In a test on the effects on Seedling Emergence and Seedling growth the most sensitive species in terms of weight was Brassica napus (Oilseed Rape) with an EC50 value for dry weight of 222 mg test item/kg soil dry weight. The EC50 value for Glycine max (Soybean) was 2587 mg test item/kg soil dry weight for dry weight. The EC25 value for Avena sativa (Oat) was 319 mg test item/kg soil dry weight for the dry weight.
Nevertheless, the test substance is not supposed to be directly applied to soil and an indirect exposure is unlikely since the log Koc is below 3 and the substance has no cationic properties. Both parameters indicate a low adsorption potential of the test substance. Therefore, binding to sewage sludge is unlikely and as a consequence a transfer to the soil compartment is not expected.
Additionally, an environmental exposure assessment was performed in order to determine possible risks of the test compound to the environment. According to the results of the exposure assessment, all the relevant uses of the test substance are considered to be safe with a Risk Characterization Ratio below 1. Hence, further tests on the effects on terrestrial organisms are not provided.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
